Hello assp-users,
I am running current ASSP 2.4.7 on port 25 with postfix 2.11.3-1 behind on
port 125. Everything is running smooth, but currently I am stuck on one
eMail which is not handled correctly on port 25.
Description:
1. SMTP commands without any abnormality (EHLO, MAIL FROM, RCPT TO, DATA)
2. After the sender did finish the data, he sends <CR><LF>.<CR><LF>, as
specified.
3. However, the server seems to ignore this, after some time the "421 4.4.2
smtp-proxy.localdomain Error: timeout exceeded" message is send by the
server.
This problem occurs only for one mail between this sender and the server.
All other emails of this sender are going through fine. I now checked the
TCP Stream, the only thing I can find here is:
- the <CR><LF>.<CR><LF> is splitted into two TCP Packets. The <CR><LF>. are
at the end of one package, after this, the next TCP Packet only contains
the 2 Bytes for the final <CR><LF>
Can this splitting be a problem or bug within assp or postfix? I can supply
the TCP dumps and stream and also the debug assp log, if necessary.
Thanks alot for your answer.
Best regards,
--
